8XC196NU CO MMERCIAL
CHMOS 16-BIT MICROCONTRO LLER
The 8XC196NU is a member of Intel’s 16-bit MCS
®
96 microcontroller family. The de vice features 1 Mbyte of
linear address space, a demultiplexed bus, and a chip-select unit. The external bus can dynamically switch
between mult i plex ed and demu ltipl exed operatio n.
